LEDs light up numerical voltage level indicators,
, or both (AC) indicators.
Voltage detection will function without batteries installed.
Instrument will vibrate in the presence of voltage
measurements that activate the 120V LED.
Vibration will function only with batteries installed.
Accuracy of indicator lights is 70% to 100% of the voltage displayed
to account for normal variations in supply voltage.
Voltage-type indicator LEDs (DC, AC) illuminate at around 12V.
The approximate input resistance of 15k
will reduce the possibility of
false readings due to ghost voltages on de-energized lines.
Molded lead holders on the back of the ET50 are spaced correctly
to test tamper-resistant outlets.
